Cylindrical roller bearings feem ntau tsis tuaj yeem tiv taus cov axial loj. Cylindrical roller bearings yog tsim los tiv thaiv radial loads. Lawv cov rollers thiab raceways nyob rau hauv kab sib cuag, tso cai rau lawv tiv taus siab radial loads, tab sis lawv axial load peev xwm yog heev txwv. Qhov no yog vim hais tias cov menyuam -kev sib txuas hauv cylindrical roller bearings tsis yog tsim los kom xa cov axial zog zoo.
Txawm li cas los xij, qee qhov tshwj xeeb tsim cylindrical roller bearings, xws li cov flanges (piv txwv li, NU, NJ, NUP qauv), tuaj yeem tiv taus qee yam unidirectional lossis bidirectional axial rog. Cov kabmob no siv cov flanges ntawm cov menyuam kawg kom txwv cov menyuam hauv qhov kev taw qhia axial, yog li tso cai rau lawv tuaj yeem tiv thaiv cov axial tsawg. Txawm li cas los xij, lawv lub peev xwm thauj khoom axial tseem qis dua li lawv lub peev xwm radial load, feem ntau tsuas yog 10% -20% ntawm lub peev xwm radial.
Hauv kev siv tswv yim, yog tias nws yog qhov tsim nyog los tiv thaiv cov radial loj thiab axial loads ib txhij, tapered roller bearings lossis angular contact ball bearings feem ntau yog xaiv. Tapered cov menyuam bearings muaj kev sib cuag ntawm cov menyuam thiab cov kev sib tw, ua rau lawv tuaj yeem tiv taus ob qho tib si radial thiab axial loads ib txhij, nrog lub peev xwm siab axial. Angular hu rau pob bearings, los ntawm lawv cov angular hu tsim nrog cov raceways, tuaj yeem tiv taus ntau dua axial loads thiab ib qho℃ntawm radial load.
Tsis tas li ntawd, axial load peev xwm ntawm cylindrical roller bearings tseem cuam tshuam los ntawm txoj kev mounting. Yog tias lub nplhaib sab hauv lossis sab nraud ntawm cov kabmob tsis raug kho, axial rog tuaj yeem ua kom cov kabmob tshem tawm, txawm tias ua rau cov kabmob puas. Yog li ntawd, thaum siv cylindrical roller bearings, axial rog yuav tsum tau zam kom ntau li ntau tau, lossis lwm yam kev ntsuas (xws li ntxiv cov kabmob thrust) yuav tsum tau muab coj los faib cov axial load.
Hauv cov ntsiab lus, lub luag haujlwm tseem ceeb ntawm cylindrical cov menyuam bearings yog tiv taus radial loads, thiab lawv cov peev xwm axial yog txwv. Nyob rau hauv daim ntawv thov uas yuav tsum tau loj axial rog, lwm yam bearings los yog ib tug ua ke tsim yuav tsum tau xaiv.
